that sounds quite like nexus preset called Uk Pikes 2 lol, i might be wrong but i think it starts with that and underneath you have that "original" saw layers which are later opening and blasting through the drop. this has nothing to do with vocals or any vocal resampling etc lol,sounds like a pretty standard combination of sylenth & nexus...trust me if you get the exact notes which are playing in the drop you gonna much closer finding that sound than just scrolling through presets =) just my 5 cents
